PNEUMATIC CARRIER;

SPECIFICATION formingpart of Letters Patent No. 382,375, dated September 10, 19 01. Application filed February 11 1801. Serial No. 46,783, (No nindelJ 1T6 all whom it mrtyemwerm B' -it k nown thatl, AUGUST WOLTMAN, a citizen of the United States of.America,'r e sid ing' at Chicago, in the-county of Cook and State of. Illinois, have invented certain new anduseful Improvements in Pneumatic Garwhich the discharge and the receivingor return tubesfare arranged side by side; and the invention consists in certain novel characteristics possessed by the terminaLpr-open by reason of which the discharge branch of the terminalfmaybe securedto theremai-nder in I a variety of diifercnt g-positions to' accommodate it tothe various requirements'which may be met in erectingthe terminal.

It also consists in certain subordinate featuresof improvement which are particularly advantageous-inthis sort of terminal, but which maybe of value inother anddiiierent sorts:

' In the. drawings shomng thepreferrediform j of the terminal, Figure l is a vertical section in the plane 11' of Fig. 4, withthe exception that the return branch of the terminal is swung into the plane of the section. Fig. 2 is a vertical transverse section in line22 of 'Fig. 1. Fig; 3isajhorizontalsectien looking upward in the-line'3 3 of Figrhiand Fig. sis an end elevation:

thearrow'et of looking ini'the direction of Fig.1 and showing the return branch swung at right angles to the position shown 'in iFig. 1.

' Referring to-thedrawings, AA" represent,

respectively, the discharge and return tubes of a pneumatic-carrier system air passing through the same in-the direction- Q. The hollow, base The terminal proper arrows shownin said tubes.-

is composed of hollow base B, surmounted. b'y'a'curved branch B is provided-with an.- opening 11 to. receive the return-tube A and an adjacent opening I) t'o, receive the dis-.-

charge-tube .A, which-is usually parallel with the return-tubeat this point in the system.

I'Ipthe" top of the base Bare two'preferably 2 circular openings, fa :r'eceivingvalve one; 12 being covered by D,,'fwhi'ch is opened to insert the carrier into-thereturn-tube, and the the current of other, b which is also preferably circular, is

covered by the bottom of the discharge branch in the formof a flange 0, Figs. 1 and 3, and the other side of-which is partially surrounded by aretnrnpa'ssagec', preferably forming a part of the discharge branch 0. This returnass'a eo eusat'c into the interior of the 'base B andat 0 into the discharge-passage .0 of the discharge branch neartheend thereof. .Said discharge passage is preferably approximately circular in cross-section, and its discharge end is covered by an ordinary discharge-valveE. The-opposite end of the discharge-passage c terminates in a circular opening 0 adapted to receive the end of the discharge-tube A. The flange c is provided with a series of perforationsand the base just-beneath said flange has inwardly-projecting lugs, biliig, 3, preferably'tapp'edto engage screws F, by means of which the di'scharge branch is'securcdto the base of the terminaL- By loosening-these screws the dis charge branch may be adjusted angularly '0, one side of which is extended horizontally I about the "axis of the discharge-tube, so as to give the discharge-endanydesired 'relative position to the retur'n-tube. In this Way said return; tube may be arranged :upon

either side of the discharge branch, back oi it, or. beneath it,asseenin -Fig. 1. This terminal may be used, therefore, as a right or, left terminal, and if neither of these ordinary positions is preferable may be given a 'variety of other positions, which are impossible in the use of the ordinary terminal except byspecial construction.-

' Thedetails of the terminal are thought to beimmaterial to the broadertfeaturesof the invention, and for that reason said invention is not limited to'th'e exact construction shown in the drawings. I

v I claim as new and desire to secureby Letters'Patent 1; in a terminal tor pneumatic-carrier sys terns, the combination with a suitable 'base provided with openings-to receive the discharge and return tubes of the system, of a curved discharge branch angularly adjust able about the axis ofthe dischargetube; sub

stantially. as described.

2'. In aterminal for pneumatic-carriersystoms, the combination of a hollow base adapted for attachment to the discharge andreturn tubes of the system, of a curved discharge branch containing a discharge-passage into which thedischarge-tube opens, a return-passage connected with the discharge-passage near the discharge end thereof, and with the return-tube at'thc other end,and meansfor securing said discharge branch in place and adjusting it angularly about the axis ofv the discharge-tube; substantially'as described. I 3. In a terminal for pneumatic-carrier systema, the combination of a hollow base pro 'vided with openings to receive the discharge and return tubes and a valve aifording access to said retu rn-tube;a curved discharge branch secured to the base and angularly adjustable thereon about'the axis of the discharge-tube,

of said discharge-passage; substantially as described. 7 v

In witness whereof-I have hereunto set my hand, at Chicago, in the county of Cook and.

State of Illinois,this-23d day of January, A. D.
